In this manner the opposite end of shaft 2 is drawn inwardlyclearing the outer face of cover plate 31. The entire brush 1 and shaftcrosssectional is then rotated upwardly and the end of shaft 2 withdrawnfrom partial spherically-shaped cup 18.

Referring to FIGS. 4, 5 and 6, there is shown another embodiment of theinvention. Brush 101, similar in construction to aforesaid brush 1, ishoused within bathtub 104, tranversely disposed between inner walls 104aand 104b and outer walls 1040 and 104d, respectively. Said cylindricalbrush is mounted on axially rotatable shaft 102 so that said brushrotates with said shaft. The shaft 102 desireably has a squarecrossectional configuration.

The end of the shaft 102a, opposing wall 104b, is slidably received inthe inner surface of an inner annular collar 103, the outer surface ofsaid collar is grooved to receive ball bearings 105 (typical). Andsurrounding the ball bearings is an outer annular collar 106 with agroove on the inner surface of the outer annular collar 106 so as toretain the ball bearing therein. This ball bearing assembly is similarto other assemblies in this embodiment as well as other embodiments aswill be pointed out hereinafter.

Fixedly attached to the outer surface of outer annular collar 106 is thelower end of a first vertical member 107 which is perpendicular dispoedto shaft 102. The upper end of vertical member 107 is fixed attached tothe outer surface of an outer annular collar 108 of a ball bearingassembly similar to the previously described ball bearing assembly; thecomponents being an outer annular collar 108, ball bearings 110(typical), and inner annular collar 109.

In operation, a person lying in the bathtub can adjust the cylindricalbrush to any height at any lateral point in the bathtub, therebypermitting numberous positions in which the rotating cylindrical brushcan contact any one of several parts of the body. For example, the legsmay be positioned under the brush or draped over the brush. Also, theperson in the bathtub may assume several postures, such as lying on theback, prostrate, or sitting, as desired, for brush massaging.

Referring now to FIGS. 7, 8 and 9, there is shown still anotherembodiment of this invention. In FIGS. 7 and 8 there is shown acylindrical brush 201, similar to aforesaid brushes 1 and 101,transversely disposed in bathtub 204. v

The drive means for rotating cylindrical brush 201 comprises a motorM-l, mounted below floor F and mounted outwardly of and below the outerwall 204a, by means of vertical plate P. The motor drive shaft 202protrudes inwardly through outer wall 204a and outwardly of the outersurface of the corresponding inner wall 204b. Mounted at the end ofdrive shaft 202 is, lower pulley 205 having endless belt 206frictionally held to the peripheral groove therein. Rewardly andupwardly of the lower pulley 205 is an upper pulley 207 of largerdiameter than the lower pulley 205.

Both of the aforesaid pulleys are disposed betweenthe outer surface of inner wall and the opposed inner surface of outerwall 204a of the bathtub 204.

Projecting inwardly from the hub of upper pulley 207 is a rotatablecylindrical connecting shaft 208 having an axial square hole 208atherethrough. The connecting shaft protrudes through the inner wall 204binto the bathtub cavity and is rotatable within bushing 209, saidbushing mounted in the inner wall and retained therein by cover plate210, said cover plate fixed mounted to the inner surface of the innerwall 204. The cover plate has a central bore 210a through whichconnecting shaft 208 slidably passes, thereby allowing the connectingshaft to freely rotate therein.

The square hole 208a of connecting shaft 208 slidably receives one end211a of square brush shaft 211 being fixedly fitted into a central bore201a at one end of cylinder 201b of brush 201.

Mounted within a central cylindrical bore 2010 at the other end ofcylinder 201b of brush 201, is a ball bearing assembly, similar to thoseball bearing assemblies as aforesaid, and having an outer annular collar212, an inner annular collar 213, and ball bearings 214 (typical).Slidably received within the inner surface of inner annular collar 213is one end 215a of cylindrical shaft 215, the other end 2l5b of saidcylindrical shaft 215 is fixedly mounted to plate 216, said plate 216 inturn being fixedly attached to the inner surface of inner bathtub wall2040. In this manner the brush 201, driven by connecting shaft 208 incombination with brush shaft 21 l is freely rotatably about cylindricalshaft 215.

Further, longitudinally disposed within the cylindrical hollow ofcylinder 201b is a compression spring 217, said spring 217, the endsthereof pressing against ends 21 lb and 215a of shaft 211 and 215,respectively. By this construction, the brush 201 may be removed fromthe assembly by first moving the brush laterally in the direction of thewall 2040, thereby compressing spring 217, and clearing end 211a fromthe inward surface of plate 210. The brush may then be cleared of shaft215 and removed from the bathtub.

Referring now specifically to FIG. 10, there is shown still a furtherembodiment of the invention. More specifically there is shown analternative construction for removing a brush similar to that of FIGS.7, 8 and 9 from the bathtub cavity. Cylindrical brush 301 comprises ahollow base cylinder 301a having circular bores 301b and 3010 at therespective ends thereof.
